RHEL6 uses the new Upstart startup service to replace the previous SystemVinit

RHEL6 accelerates the startup by replacing SystemV with Upstart. With this new service, RedHat can still maintain its backward compatible management mode, which means you can still use the original method to manage the service.

RHEL 6 accelerates the startup by replacing System V with Upstart. With this new service, RedHat can still maintain its backward compatible management mode, which means you can still use the original method to manage the service.

The/etc/inittab is only used to configure the default running level of the system. All entries previously set by the/etc/inittab exist in the/etc/init/directory as a single file.

/Etc/init/rcS. conf sets the initialization of the system by starting most basic services.
/Etc/init/rc. conf
/Etc/init/control-alt-delete.conf defines the system behavior when the user presses the "control-alt-delete" three keys
/Etc/init/tty. conf and/etc/init/serial. conf define system processing terminal Login

In addition, active_les les in/etc/sysconfig/init determines the creation of the virtual console, whether AUTOSWAP automatically detects swap partitions, and the SHELL used by root in SINGLE-user mode, the default value is/sbin/sushell. In addition, the logon prompt is displayed before/sbin/sulogin starts in single-user mode.
